Inqola yesandla yokunqamula i-voltage ephezulu iwuhlobo lwemishini esetshenziswa kusistimu yamandla kagesi aphezulu, esetshenziswa kakhulu ukunqamula isekethe ukuze kuqinisekiswe ukusebenza okuphephile kohlelo lwamandla. Leli phepha lizokwethula isimiso sokusebenza senqola yesandla yesinqamuli samandla kagesi aphezulu.
Inqola yesandla yesinqamuli somfutho ophezulu yenziwe ngommese onqamulayo, isibambo, indlela yokudlulisa, ubakaki nezinye izingxenye. Ummese onqamulayo uyingxenye eyinhloko yale nqola yesandla, futhi usetshenziselwa ukunqamula isekethe. Imimese yokunqamula ngokuvamile yenziwe ngethusi futhi inomoya omuhle wokusebenza kagesi nokumelana nokugqwala. Isibambo sisetshenziselwa ukulawula ukushintshwa kommese, futhi indlela yokudlulisela iwukudlulisa amandla esibambo kuso, ukuze sikwazi ukwenza umsebenzi wokushintsha. Ubakaki usetshenziselwa ukusekela izingxenye zommese onqamulayo kanye nendlela yokudlulisela.
Umgomo wokusebenza wekalishi lesandla elinqamula amandla kagesi aphezulu ukulawula ukushintshwa kommese onqamulayo ngesibambo, ukuze ubone ukuhlukaniswa kwesekhethi. Uma isibambo sivaliwe, ummese wokunqamula uxhunywe kumjikelezo, futhi okwamanje ungadlula ngokujwayelekile. Lapho isifunda sidinga ukuhlukaniswa, opharetha uzungeza isibambo ukuze ahlukanise ummese wokunqamula kumjikelezo, ngaleyo ndlela afeze ukuhlukaniswa kwesifunda. Uma uhlukanisa isifunda, kuyadingeka ukuqinisekisa ukuthi ibanga phakathi kommese wokunqamula kanye nesifunda likhulu ngokwanele ukugwema ukukhiqizwa kwama-arcs kagesi.
Ukusetshenziswa kwenqola yesandla yokukhipha amandla kagesi aphezulu kudinga ukunaka amaphuzu alandelayo:
1. Ngaphambi kokusetshenziswa, kuyadingeka ukuhlola ukuthi ummese onqamulayo kanye nendlela yokudlulisela ijwayelekile yini ukuze kuqinisekiswe ukuphepha kwemishini.
2. Gcina isibambo sizinzile phakathi nokusebenza ukuze ugweme ukulimala kwedivayisi noma ukulimala komuntu siqu okubangelwa ukuzungezisa isibambo.
3. Uma uhlukanisa isifunda, kuyadingeka ukuqinisekisa ukuthi ibanga phakathi kommese wokunqamula kanye nesifunda likhulu ngokwanele ukugwema ukukhiqizwa kwe-arc.
4. Kudingeka ukuhlanza nokugcina okokusebenza ngemva kokusetshenziswa ukuze kuqinisekiswe ukusetshenziswa kwempahla isikhathi eside.
Inqola yesandla ye-high voltage disconnector iyisisetshenziswa esibaluleke kakhulu, esingaqinisekisa ukusebenza okuphephile kwesistimu yamandla. Kuyadingeka ukunaka ukuphepha lapho usebenzisa imishini futhi ulandele imithetho yokusebenza ukuze uqinisekise ukusebenza okujwayelekile kwemishini nokuphepha kwabasebenzi.
